Use the Go language to pack an AAR package for Android

One, Environment construction

1. Install Go

A. Download address: https://golang.org/dl/

B. The version downloaded here is Go1.5.2.windows-amd64.zip

C. Then unzip the Go folder inside the tarball to the D packing directory

D. Configuring environment variables Goroot and Gopath

E. Goroot value is D:/go

F. New Folder D:/gopath

G. Setting the environment variable Gopath value to D:/gopath

H. Increase in the PATH environment variable;%goroot%/bin;%gopath%/bin

2. Install Go Mobile

$go Get Golang.org/x/mobile/cmd/gomobile

→ If you cannot access golang.org, you can access https://github.com/golang/mobile, download the source program directly, and copy the Mobile folder to the $GOPATH/src/golang.org/x/

Perform $go build Golang.org/x/mobile/cmd/gomobile

$go Install Golang.org/x/mobile/cmd/gomobile

Gomobile.exe generation can be found under $GOPATH/bin after completion

3, affiliate Android NDK (recommended to use Android Tudio download)

$gomobile init-v The directory of your NDK

4, write Go program, I casually write a paragraph

Package Gotestfunc

ADD (x int, y int) int {

return x + y

}

In the go language, note that functions must be capitalized before they can be exported.

5. Compiling go

On the command line, CD to the directory where your. Go file is located, then execute the command

Gomobile bind-target=android

An. aar file is generated when you finish running

6. New Android Project

Open Android Studio, create a new project, select your project right-click New in the left Project panel, select module, choose Import Jar/aar, select the AAR file created in step 5th.

7. Import

Add the imported module to the created project dependencies in project structure.
